7 Claims. V(01.*12-142) This invention relates to improvements in shoesand outsolesthereor and to'mprovements in methods of. making shoes. f

An outsole which is to be attachedtoa shoe by through-and-throughlstitchesis ordinarily.. provided in its tread side with a marginalchannel .in whichV the Vsole attaching stitches are received, and achannel ap integral With'the'fsole lwhich is raised to'open thechannelfor the reception of the stitches and is subsequently laid andcemented in place to close the channel and The channel' is usually soout as to form a thin edge at the freeouter exnate the tendencyfoi vthestitch-covering `flap of c outsoles to peel or become disconnectedfromthe soles. i Y YWith this object in view I providein vthe tread side ofan outsole, 4a marginalchannel so cut as toV form a stitch-coveringchannel apjandalso a Y, tremityof the channel flap and the thnfedge lipadjacentto the free edge of the'lap foroverlapping the latterso as toVlock theiiap in-stitchY covering position andthus positively to holdthe ap against any tendencyto peel during the Wearing of the shoe. Asherein illustrated',V the# channelis formed by two angularlydisposed-cutis, l

' a relatively shallowcut extending from thetread face of lthe soletoward the sole edge at a substantial angle to the tread-face, and arelatively de ep` cutextending inwardly from the bottom of theshallowcut in a plane substantially parallel Ato the tread face. The shallowout forms a bev-y eled edge at the free outer extremity of the channelflap and it alsoV forms-'a lip having an underv cut side or shoulder,Voppositeto the beveled edge 9 of the channel flap, which is adaptedtoengage and overlie the edge ofthe flap when the flap is' inposition toclose the channel and whichthus serves most eiectively to hold or lockthe flap in piace and to protect-the edgeof the flap from wear. Theinventionis not limited, however,. to the provision of a-ohannel flapand a lockinglip bythe making of channel cuts of the partioular formandV arrangementjust described, it being essential only that Vthei-ip beadapted lto overlap the; edge portion of the hannellap when the latterisin stitchcovering position. v ,y
